Some important turns on this chapter. MC dense as fuck as always - the product of a relatively peaceful and advanced society. He can only see as far as economic development via civil works. Meanwhile valettas insecurity and the product of a violent and ruthless society has turned her to seek strenght through arms instead. She wants to be Strong, not Smart. No idea how the MC will react when she shows him she's used his knowledge to raise military might. Meanwhile, Lieze has taken the capitalist world building approach. Not necessarily what MC is after but closer than what Valletta is doing.
